Providing location-based call forwarding within a mobile telecommunications network
First Claim
1. A method for providing location-based call forwarding data to a mobile switching center (MSC) serving a mobile station within a mobile telecommunications network, said method comprising the steps of:
- receiving a signal at a home location register (HLR) indicating that said mobile station is currently within a service area associated with said MSC;
retrieving a predetermined set of call forwarding data designated for use within the service area within which the mobile station is currently located; and
providing said retrieved predetermined set of call forwarding data from said HLR to said MSC for call forwarding use when said mobile station is located within said service area.

Abstract
Call forwarding data, including forward to numbers for a particular mobile station are correlated with a particular service area and stored at a home location register (HLR) associated with that particular mobile station. Whenever the mobile station travels into a mobile switching center (MSC) serving that particular service area, the MSC performs a location update with the HLR. A location update signal further includes data representing the identity of the service area currently serving the mobile station. Upon receiving the location update signal from the serving MSC, the HLR analyzes the received data to determine the identity of the service area currently serving the mobile station and retrieves the call forwarding data associated with that particular service area. The retrieved call forwarding data are then analyzed to determine whether the forward to numbers are located in the current service area for the mobile station and, if so, transmitted back to the serving MSC in order to provide location-based call forwarding to the roaming mobile station.
